Answer:
114 it think but maybe not
Step-by-step explanation:

That is true i do believe
(a) Find the value of x.
Sum of interior in a triangle = 180
So m<BAC + m<ABC + m<BCA = 180
4x + 10 + 5x + 18 + 3x - 16 = 180
12x + 12 = 180
12x = 168
x = 14
(b) Find the measure of <3.
<3 + <BCA = 180
<BCA = 3x - 16 = 3(14) - 16 = 26°
So
<3 = 180 - <BCA
<3 = 180 - 26
<3 = 154°
